【Abstract】 The traditional tobacco raw material warehouse has some disadvantage factors, such as low efficiency of goods in and out warehouse, high cost of operation and service, errors caused by human operation, which would be negative for cigarette enterprise to improve efficiency and market competitiveness. The theme of the paper is the "Design and optimizing operation of Tobacco Raw Material Blending of Automatic Storage and Retrieval System", which is combined with the actual requirement of the automated warehouse of the cigarette enterprise. The results of this study would impulse the improvement of efficiency, cost-reducing of operating and servicing, and development of the market competitiveness of the enterprise.Base on the modern advantage design technique, this paper consider the warehouse function with the whole condition from all of the design parameter. The paper expatiate the function, requirement, structure and the class of the automated warehouse in detail. Introduce the working process of TRMB-AS/RS especially. Design TRMB-AS/RS with scientific method by the requirement of the system.Base on the theory of Agent, the control method of product according to the needed of the tobacco factory base on Agent theory is put forward. This paper analyses the problems in the production and operation process of the tobacco enterprise and put forward the necessity for the enterprise to develop the production and management system. Put forward the theory of the product according to the needed of the tobacco enterprise base on the properties and the characteristics of Agent. Build the whole frame of the product according to the needed of the tobacco factory. This frame divides the departments of the factory to be the Agents, by the cooperation between which to finish the more and more complicated production work. Build a fuzzy neural network model, by which the enterprise could study the ways dealing with the accident to empress the retractility and agility of the network model. By the method above, keep the production and management system of the enterprise to work stably and efficiently.Basing on the designing theory and the working optimization principle of the stacker, explain the working principle and the optimization design of the stacker, which is the most important part in the automated warehouse.
